Improve detection of missing compiler flags: move "argument unused
during compilation: .*" pattern from language-specific branches into
the common list.
This patch adds support for tracking the swiftmodules for executables
exporting symbols.
This fixes a bug in the earlier implementation around emitting the
swiftmodule. Previously, the code would use
`CMAKE_EXE_EXPORTS_Swift_FLAG` to inject the `-emit-module`, and module
path information into the `CMAKE_Swift_LINK_EXECUTABLE` rule. Because
Swift skips the build step and only runs during the link phase, these
flags were injected in `cmNinjaNormalTargetGenerator::ComputeLinkCmd`
instead of `cmLocalGenerator::GetTargetFlags` where it is done normally.
Unfortunately, injecting in `ComputeLinkCmd` didn't do anything because
we have a `linkCmd` so `ComputeLinkCmd` exits early, before the
EXE_EXPORT flags get added to the link command.
Instead of playing with that flag, CMake checks
`CMAKE_Swift_LINK_EXECUTABLE_WITH_EXPORTS` and uses that as the link
rule if it exists and falls back on `CMAKE_Swift_LINK_EXECUTABLE`. I've
defined that variable in terms of `CMAKE_Swift_LINK_EXECUTABLE` with the
necessary additional flags for emitting the swift module instead. This
has the same end effect as the desired behavior, but simplifies things a
bit.
Since we're generating the swiftmodule for executables with exports,
I've also updated the dependency graph to include the swiftmodule as an
output in the build dependency graph if the executable has exports.
Tests updated:
- RunCMake/NoWorkToDo:
Ensure that the build graph does not result in unnecessary rebuilds
with exporting executables.
- SwiftOnly:
Ensure that we can consume functions defined in the executable by a
library getting linked into said executable.
Prior to CMake 2.8.4 (released in 2011), we defined `WIN32` on CYGWIN.
That was removed, but an undocumented `CMAKE_LEGACY_CYGWIN_WIN32`
compatibility mode was left to help projects transition. Only projects
that do not require at least 2.8.4 as their minimum CMake version need
the compatibility mode. We've also long warned about projects that do
not require at least 2.8.12, so it is now reasonable to remove the
legacy compatibility mode.

Replace old-style `file(APPEND .../CMake{Output,Error}.log)` logging
with calls to `message(CONFIGURE_LOG)` to record the steps in the
`CMakeConfigureLog.yaml` configure log instead.
Issue: #23200
`try_compile` and `try_run` now automatically log checks using them to
`CMakeConfigureLog.yaml`.
Add `LOG_DESCRIPTION` arguments to some `try_compile` calls to
replace the description previously written to the old logs.

Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 15.

Without this, building a shared Swift library with `CMAKE_SYSTEM_NAME=iOS`
produces the error `ld: unknown option: -soname`. iOS is an Apple platform,
and so should use the `-install_name` option.
The IntelLLVM compiler, for compatibility with MSVC on Windows, always
runs with support for at least C++14. The `-Qstd=c++11` flag just
causes a warning that it is unused.

Update the logic added by commit ef41d49812 (Fix implicit include
directory extraction for adaptive relative paths, 2019-04-08,
v3.14.2~5^2) to account for the new `try_compile` work directory used
for the ABI check since commit 2edf0fc6d7 (Modules: Use new
keyword-dispatched try_compile signature, 2022-09-13,
v3.25.0-rc1~144^2).
Paths relative to the work directory will now have one more `../`
in them, so update the test data to match.

Intel oneAPI 2023.0 added the `icpx` compiler front-end on Windows.
It uses a GNU-like command-line, and is not yet supported by CMake.
Avoid finding `icpx` as the CXX compiler on Windows until support
is added.

Update the list of known versions.
There is a new header-only library, Boost.URL. It has no
dependencies and has a core header `<boost/url.hpp>`.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_81_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.81.0 source tree.
They are the same as 1.80's dependencies, so just update
the version check for warning about newer versions.
Add the `SYSTEM` flag for include directories provided by MATLAB, as the
the pragmas used are not compatible with GCC and generate a warning.
Fixes: #24166
